FAQ 2CBH Format

Can I use my older databases in the old data format with the new version?

Yes you can continue to use and edit databases in the older database formats. Since the new data format does not support some of the new features, you should generally work with the new data format *.2cbh. The conversion works in both directions (new and older data formats without any problems).

Can I use my backup copies in CBV format with the new program version?

Yes it works. In the file selection dialog, open the CBV backup copy you want to open. If you archive a database in the new 2CBH format, you cannot open this archive file with older program versions or our chess programs. The new data format is not supported by the older program versions at the time of this documentation!

So if you want to pass on a backup copy in CBV format, first convert to the older CBH format and make a backup copy of the CBH database in CBV format.
